Aye. Shouldn't there be a note in the ED calling this out as an open issue?

So the 4th length is omitted from the computed value of text-shadow?
I think it has been mentioned previously in the list that text-shadow was spec'ed before spread radius was added in box-shadow. Thus, the text-shadow definition
assumes 3 lengths, even though it doesn't explicitly restrict text-shadow to 3 lengths. So, technically, a spread radius should be allowed but the way it should work is not specified anywhere (there was a recent discussion about spread radius in text-shadow: http://lists.w3.org/Archives/Public/www-style/2011Feb/0796.html ).
The only UA currently implementing a spread radius in text-shadow is Trident.
My point is that the issue you are pointing out with the text-shadow definition is actually part of a much bigger one.
